  • Effectiveness of physical material shields in reducing atmospheric muon flux 

    Veghal, Navjeet; Lin, Keyan; McCready, Aidan; Gould, Duncan; Sterne, Connor (2022-06)
    In this experiment we studied the ability of lead to shield against cosmic ray muons. We built detectors that used plastic scintillators, silicon photomultipliers, and amplification circuits. We filtered out other ionizing ...
  • Using Beta Decay to Find the Mass of a Neutrino 

    Lo, Jess; Holleran, Laura; Allman, Ciaran; Lu, Daniel; Amodeo, Daniel; Li, Yuchen (2022-06)
    The goal of this experiment is to measure the mass of a neutrino via the study of beta decay. The motivation for this is to see how well a crude laboratory set up can determine the mass of a neutrino in comparison with the ...
  • Refraction of a Laser Beam in Various Mediums Due to Ultrasound Waves 

    Cabrera, Sierra; Clement, Jacob; Lenzi, Christiano; Sheahan, Mira; Withers, Tai (2022)
    Gas-Coupled Laser Acoustic Devices (GCLADs) are systems used to detect sound using a laser [1]. If implemented in a bubble chamber (a type of experiment used for particle detection [2]), the sounds made by bubbles forming ...
  • Electron spin resonance spectrum of pyrene and N,N-dimethylaniline free radicals 

    Kingsley, Max; Mast, Madelynn; McLeish, Brody; Pressman-Cyna, Ry; Widmer, Megan (2022-05-24)
    In this experiment, the objective was to use ESR to determine the minimum number of quantum entanglements that occur in a free-radical system. This was done by creating a saw-tooth shaped magnetic field generator that ...
  • Measuring the Work Function of Metals Through the Photoelectric Effect 

    Mcnichols, Colin; Gaudreau, Isaac; Wang, Morgan; Yuan, Minxuan; Meng, Qingzhou; Machado, Andre (2022)
    By reproducing the photoelectric effect in a vacuum environment, this experiment aims to analyze the relationship between work function value and properties of metal; specifically, binary alloys’ purity and temperature ...
  • Paschen’s Law in Different Gases 

    Maves, Jackson; Hewitt, Brady; Campbell, Kathryn; O'Keefe, Ethan (2021-05-27)
    An experiment was performed to measure the Paschen curves of multiple gasses. Paschen curves are generated using Paschen’s equation. A plasma discharge tube was used to induce arcs of plasma in low pressure environments ...
  • Undergraduate Construction of an Optical Tweezer Apparatus with a Study of Brownian Motion on Micron-Sized Polystyrene spheres 

    Bisson, Yannich; Bucciarelli, Dean; de Lint, Maaike; Hasting, Daniel; Jafs, Michael; Reed, Madison (2021-05-26)
    In this experiment, an apparatus is designed for use with optical trapping of polystyrene spheres with diameters ranging from 1-5 µm. The goal of the experiment is to first construct a working apparatus that is capable ...
  • Optical Trapping: Final Report 

    Bisson, Yannich; Bucciarelli, Dean; de Lint, Maaike; Hasting, Daniel; Jafs, Michael; Reed, Madison (2021-05-26)
    The Optical Trapping experiment uses the momentum of photons from a laser beam in order to apply a trapping force onto 4.5 µm diameter polystyrene microspheres. When trapped in this way, the spheres behave much like they ...
  • Examination of low temperature argon plasma by optical emission spectroscopy and comparison with Paschen’s curve. 

    Micuda, Ashley; Lismer, Tristan; Ter Horst, Sam; Wormington, Reegan (2021-05-11)
    In this experiment we studied argon plasma at room temperature by varying the voltage and pressure of a plasma chamber for ten different samples. Our experimental measurements aligned with the theoretical optical emission ...
  • Temperature’s Effect on the Speed of Light 

    Xie, Anne; Chu, Jessica; Xie, Luyao; Zhao, Kun (2021-05-04)
    In this experiment, our group investigates the effect of temperature on the speed of light by experimentally measuring the change in the angle of refraction through common glass over a 100C range in temperature while ...
